I am more worried about how this affects the charging infra rather than tax credits on leases/purchases. Infra is possibly a big reason for the seemingly saturated EV market at present in the US. I suppose the IRA had some good funding towards charging infra. I am not sure if flow of those funds can be interrupted as the infra work is expected to be ramped up in 2025 onwards. Anyways, it is very likely that it will go away if there is a way. That will put a serious pressure on companies in making more EVs. Traditional companies can go back to making hybrids. Or, they can fund the infra projects and work towards an accelerated transition. It's their call.
